The Integrated Amplifier which inherited the technology of S series and carries
In order to solve the opposite problem of delicate power of expression
and a speaker drive, "large current type magnification element UHC-MOS"
which also has the 3 to 10 times [ usual ] as many current supply capability
of peak current 120A in an output stage is adopted.
UHC-MOS is an element which
current supply capability is improved a bipolar transistor and more than
equivalent, and also has a sound quality merit of MOS-FET, and the variation in
magnification operation is canceled by carrying with single push pull
L. C (Leakage Canceling) mount twin transformer is adopted.
The twin transformer parallel connection which improves sharply the
characteristic of each magnetic circuit and winding wire circuit developed by
monophonic power amplifier POA-S1 of DENON is adopted. Moreover, by considering
influence of magnetic etc. as the L.C mount canceled mutually, the leakage flux
of the power transformer used as the noise source in amplifier was reduced, and
high current supply capability and low-noise-ization are realized.
technology developed by Integrated-Amplifier PMA-S1 of DENON is adopted as a
While using the large-sized high-speed rectification
diode (first recovery diode) excellent in large current supply capacity and
aiming at correspondence to a high speed and large current, the high-quality
sound capacitor is used for a power source capacitor.
In order to cancel
degradation of the sound quality by the mutual intervention between circuits, or
inflow of a noise, it had composition which made the power amplifier block
become independent, and also the block structure which also separated the
circuit where other signal levels differ is adopted. This has eliminated the
influence on the sound quality by the interference during each block.
Moreover, since a chassis examines and uses the thickness of a copper plate
in order to secure high rigidity, and also the right comb of vibration is put
into practice, a transformer base and special rubber have been added to the
power transformer part.
gilding processing is performed for carrying out
brass shaving appearance, and more reliable connection is enabled in the speaker
Moreover, two terminals are carried and bi-wiring is supported.
The pre-out terminal is carried.
The first rank circuit of
discrete composition of having used low-noise FET is adopted as a phone
Moreover, both of the cartridges of MM/MC can be used by the
change of a switch.
A gilding terminal, carbon resistance, a capacitor,
etc. are using the reliable part.
Moreover, in order to lower power-source
impedance, the inlet type very-thick power cord is adopted.
remote control is attached and CD, the cassette deck, and the tuner are also
Moreover, circuit power sources for control, such as remote
control, equip the independent power transformer, and are considering it as the
composition which makes interference to an audio circuit the minimum.
Two kinds of variations, gold and black, occurred.
